This came from the tilt-back 10" speaker model, bought it to have a smaller portable rig around and just discovered I can slide my Shuttle right into that space (cool!)...so this can move on to someone else. You could put it into a frame, attach a speaker to the leads (or just use the external spkr jack), retrofit to another combo, or use as a practice/headphone amp (has phones out and aux in with adjustable level). Paypal works for me. Here's some pics. PM with questions, etc...
And one with the chassis still sitting in the combo:
thanks
